Rear wheel bearing - rusted/stuck, can't remove

Hello everyone,
Still working on my Dad's Volvo. Thought I got all the hard stuff out of the way (coolant leak, P/S leak, sunroof rattle...), and was going to "knock out" this wheel bearing thing Thursday night. Well it's Friday and still no luck.
Got everything off around the bearing, and the 4 bolts out the back, so it should just come off right? No ... not after plenty of whacks with one of the largest dead blow hammers I could find. This "persuader" has worked in plenty of other situations for me but not this time. Bearing has soaked in PB blaster (which has been applied repeatedly) for 24 hours. Still nothing.
Any ideas of what next? Thankfully I have another car to use in the meantime.
Ideas:
1) Get a sledge / bigger hammers
2) Rig up something to thread through the wheel bolt holes (on the hub face) to get leverage and whack on that too

Here's an idea.....we'll make the car do all the work. Put the bolts back in that hold the hub in the knuckle, but don't tighten them up all the way. Leave them loose about 1/8" clearance between bolt head flange and back of knuckle. Put the wheel back on the car, and bolt it up. Then lower the car back down on the ground and, with an assistant, start pushing the ass end of the car side to side.....see if the weight of the car will break the hub loose. Once it has done that, then jack it back up and carry on as per usual.

and give it some heat on the next try

NO, don't use heat. You'll damage the backing plate, plus you don't ever use heat around an aluminum component such as a steering knuckle. It won't do anything anyway except swell up the hub and possibly crack the knuckle.

Did you get the PBlaster in the joint between the bearing carrier and the suspension arm? There are a lot of things going on there and it can be tough to see but if you've soaked it good, try putting a bit of heat on the joint. Perhaps that will allow the PB to soak into it.

When I did mine, the first few whacks with a dead blow didn't do it, but I used Deep Creep (made by the makers of SeaFoam) and managed to get it in the joint. A couple of good whacks at that point and the thing just fell off.

I had similar difficulty with removing the rear bearings. I ended up fabricating somewhat of a reverse gear puller (a gear pusher) out of some 3/8" threaded rod and some steel angle iron. I would tighten the nuts on the rod to put outward pressure on the bearing and with a hammer run around the circumference of the bearing and little by little it started to inch out and then finally it just popped out.

Success!!

Hey guys,
The winning technique goes to a 10lb sledge and half a can of deep creep. I just kept spraying the joint (as mentioned below) between the bearing and the mounting face. Saw some of the foam come out the sides and kept going. Got inspired and about 20whacks with the sledge later it came off.
In fairness, this is all I had done:
Quarter can PB blaster and about 50 whacks with a 4lb dead blow.
Entire can of CRC freeze off and about 20 whacks with the 10lb sledge
Then finally,about a half of the deep creep can and 20 whacks with the sledge.
